Underwater acoustic channel is a challenging medium for communication due to the
presence of significant multipath, high noise, frequency‐dependent propagation loss, and …

Visible light communication (VLC) is a disruptive technology that uses light-emitting diodes
(LEDs)/LASERs to transmit data wirelessly using visible light spectrum. VLC has many …

Underwater acoustic (UWA) communication is the only option for underwater long-distance
wireless communication. However, its data rate is very low, in tens of kbps, and the time …

In underwater acoustic communications (UAC), signal synchronization plays a key role in
the performance. It is usually performed using a known preamble transmitted prior to the …

In this paper, we investigate the performance of HFM signals for timing synchronization in
underwater acoustic communication systems. The considered HFM signals are comprised of …

Chirp slope keying (CSK) modulation based on linear frequency modulation signal (LFM)
and hyperbolic frequency modulation signal (HFM) combined with passive time reversal …

Due to being easily affected by the environment, underwater acoustic communication and
underwater optical communication are not suitable for small underwater robots …

This work considers the problem of false frame synchronization for underwater acoustic
communication (UWAC), and a new frame synchronization approach based on Linear …

This article is devoted to the comparison of preambles for signal detection in underwater
acoustic (UWA) communications. The main feature of the UWA channel is the strong …

In this paper we propose and analyze a new approach for synchronization of OFDM based
underwater communication systems with significant Doppler spread. In order to keep cyclic …
